If I run my battery down to about 20%, then with a 100W USB-C charger I see a good 4.5+ amps consistently. By 40% battery level it slows to about 3A. (I have the same TC66 usb-c meter, it’s great)

After figuring out the compatible power brick & cable combination I’m able to get 61+W to the battery
However the power cuts down before 40% and the input power lower than 20V2.7A, likely due to battery overheating since the voltage is still well below 17.8V and if charging starts capped at 20V2.7A input it’ll maintain this current up to 75% charge instead.
One big advantage of Linux compared to Windows is that the CPU stays underclocked when idling even when plugged in. On Windows the CPU often overclocks at 1% CPU load when plugged in even if you select “power saver” or “better battery”, not to mention the suspicious high CPU usage & fan speed when AFK.
I think that the reason that many users’ battery degradation is worse than claimed 80% capacity after 1000 cycles. Battery testing is done in “ideal” conditions, i.e. 23~25 degree Celsius, 0.2C constant current charging, 0.03C cut-off at constant voltage and 0.5C discharging. In actual use the temperature is much higher, charging C rate is higher and the charging SOC is also higher (charging from 75% to 85% 10 times is worse than charging from 0% to 100% once).
Hey, what is the ETA for the full firmware release @Kieran_Levin? I’m hoping it solves AMD7840U/ GPD Win Max 2 (2023)/ DMI board G1619-04: Hibernation (S4, suspend to disk) or resume hang randomly. (#3168) · Issues · drm / amd · GitLab

No more BSODs since upgrading. I was getting them occasionally and haven’t had any since upgrading.
Hopefully, Framework/Insyde can update us on AMDs mitigation for LogoFail.

awesome, me too
would you confirm also getting

My charger STILL doesn’t work on this update.
https://satechi.net/products/165w-usb-c-4-port-pd-gan-charger
I have to plug my phone in to the second port, then unplug it to trigger the charger to actually work on my laptop otherwise the charging indicator just goes on and off and it doesn’t seem to charge.
I bought a USB PD GaN charger which is supposed to be the spec and I’ve had to do hacky work arounds for 3 months with no feedback until a beta bios update that doesn’t even address the issue.
Like guys- I love this laptop, but this and the random blue screens are a joke. At least tell us what’s happening- we’ve had nothing but silence until this update which hasn’t even resolved the issue. Clearly something is wrong with power negotiation because once I do this workaround I can leave the laptop plugged in by itself for as long as I want but if I unplug the laptop I need to do it over again.
The specific USB-PD bug that this update fixes is described in the first posts by @patagona here: AMD Framework USB-C charger compatibility issues
USB charging negotiation is probably the most complicated charging scheme in consumer electronics. There is room for many different bugs in both chargers and devices, and some sloppy leeway to allow some bugs to be tolerated or worked-around in some cases, so it’s really hard to assign specific blame, unless you have some kinda expensive equipment and expertise to analyze the situation. Even the cables need chips in them to tell the device it can pull more than 3A through the cable (and probably max voltage too for higher voltages, I’m not sure).
In your case, plugging in your phone first affects the voltage/current offered on the other ports of the multi-port charger, and it depends on which specific ports too - in some cases the laptop is still offered 100W after the phone is plugged in, in other cases it’s only offered 60W. My guess is you need to get the charger in this 60W offering mode for the laptop to charge, the 100W mode doesn’t seem to work between that particular Satechi charger and the Framework 13 AMD and the particular usb-c cable you use. Exactly why, I have no idea, but it can be complicated. Bad luck, sorry.

That sounds super unsustainable (more e-waste on chips) and unreliable (another point of failure). I prefer the traditional way of measuring voltage drop/internal resistance to get whether to draw max current and I don’t want to buy yet another cable specifically to beg for 48V
I have a similar problem, when plugged into a 4 port UGreen power brick the laptop only draws 2.7A the majority of the time as I mentioned before even it draws 2.93A with a 5V3A supply using the same cable, and when the power brick is connected to another smartphone, the laptop will draw 20V2.93A instead of 2.7A, very strange.
EDIT: 5V3A input doesn’t work, I misread the meter as it showed the computer was powering the power bank
Measuring voltage drop was never a thing in laptops, charger-id before was either a resistor divider on the center pin or in some cases some form of onewire eeprom to read how much it can draw from a power supply. Since the cables were part of the psu the computer didn’t also need to know the capabilities of the cable. It’s a safety feature and makes sense as long as there aren’t too many bad actors putting 5A e-markers into cables that’ll melt down at 5A.
48V needs e-marker for a whole other issue, 48V needs better built connectors cause it’ll arc harder if you unplug it under load.
Power sharing implementations in multi-port chargers can get very weird
I found an interesting way of identifying of whether a cable has e-marker chip. On the TC66 both PWR and PD switch ON, connect the TC66 to a power brick, it’ll negotiate 5V. Then plug in your cable after that. If the TC66 switches of the cable has e-marker, if it stays on the cable has no e-marker.

Can anyone confirm the sha1sum of the *.cab is 892d03afc0bb80dd358f5e076667e4191ec35870 ?

Can any dev confirm the checksums for the 3.03b releases? I’m not to keen on installing a standalone file especially if it’s a bios update without verifying it first.

Not dev, but I got success flashing with

The fact the we all have the same hash is irrelevant. We need to know what it is before they supply us with the file.

Thanks for bringing this up. I verified the hashes on the files before they were uploaded to our download site and added them to the first post.
We will include hashes in future releases for everyone.
The windows updater always is signed by the framework EV key, and timestamped.
For the security paranoid, our windows EV certificate is going to be rotated next month, as the current certificate will expire.

Appreciate it. @Richard3 is correct though, the hash is only useful before installing it and it has to come from dev team, they are the only ones who know the genuine hash. No point in installing then checking, hash is meant to check against tampering so you don’t install something malicious.
Good stuff. Thanks
Hope this is the real you and not some imposter 
@Kieran_Levin do you have any idea when this 3.03b release turns into an official one. At least I got the impression it is a beta release.
